Researchers at Massachusetts Institute of Technology were able to develop an ultra-sensitive magnetometer that is nearly 1,000 more energy efficient than current devices.

Magnetometers, or magnetic-field detectors, have a wide range of applications in medicine, but they are also used by the police to detect arms trafficking and geologists that want to have a more accurate image of the variations in the Earth magnetic field.
